Eggplant Flour Addition in Cookie: Nutritional Enrichment Alternative for Children.

This research aimed to evaluate the effect of adding different levels of eggplant flour in cookie on the physicochemical and nutritional characteristics and to verify the sensory acceptability among children. Four eggplant flour cookie formulations were prepared: EF0 (or standard), EF2.5, EF5.0, and EF7.5 (Eggplant Flour 0, 2.5, 5.0 and 7.5%, respectively). The sensory acceptability, physicochemical and nutritional composition were evaluated. The eggplant flour addition of 7.5% to cookie reduced the acceptability (p > 0.05). The samples EF5.0 and EF7.5 showed higher diameter, expansion and thermal factor, while the EF0 and EF2.5 had higher thickness (p < 0.05). The flour addition significantly increased the hardness, Water activity (Aw), Titratable Acidity (TA) and Soluble Solids (SS) in the cookie, however, L* a* and b*, pH and SS/TA ratio values were reduced (p < 0.05). Increased levels of ash, dietary fibers, ascorbic acid, anthocyanins, total phenolic compounds and antioxidant activity were verified on the cookie after eggplant flour addition. Meanwhile, there was a reduction in energy and carbohydrate values. It is concluded that eggplant flour addition up to 5% in cookie maintains the sensory acceptability similar to the standard product when evaluated by children. In addition, it can be considered a viable alternative to improve most of the physicochemical and nutritional characteristics of the product.

Combination of cafeteria diet with intraperitoneally streptozotocin in rats. A type-2 diabetes model.

PURPOSE: To develop a model of induction of type-2 diabetes (DM2) by combining low doses of streptozotocin (STZ) and a cafeteria diet. METHODS: Forty male Wistar rats (200 g) were allocated into four groups: control (non-diabetic, n = 10); STZ 30 mg/kg (diabetic, n = 10); STZ 35 mg/kg (diabetic,n = 10); and STZ 40 mg/kg (diabetic, n = 10). DM2 was induced with a single intraperitoneal injection of STZ after four weeks of cafeteria diet in the three diabetic groups. All animals were evaluated as for anthropometric, and biochemical analyses, as well as liver, kidney and pancreas histological analyses. RESULTS: Lower weight gain, higher water intake, higher Lee index, hyperglycemia and modified total protein, urea, alpha-amylase, as well as insulin resistance, hepatic steatosis, pancreas, and kidney injury were observed in animals treated with 35 and 40 mg/kg of STZ. CONCLUSIONS: The results show that the experimental model using cafeteria diet associated with 35 mg/kg of STZ is a low-cost model and efficient in order to develop DM2, confirmed by the presence of polydipsia, hyperglycemia, altered biochemical tests, insulin resistance and damages to the liver, pancreas and kidney, which is similar to the disease found in humans.

Addition of Orange Peel in Orange Jam: Evaluation of Sensory, Physicochemical, and Nutritional Characteristics.

Orange is highly nutritious and a source of phytochemical compounds. However, its by-products are usually discarded. In this study, we evaluated the effect of orange peel (OP) addition in orange jam on sensory, physicochemical, and nutritional characteristics. Four jam formulations were elaborated with different OP levels: OP0 (standard), OP4, OP8, and OP12 (Orange Peel 0, 4, 8 and 12%, respectively). All samples were evaluated for sensory acceptability, and physicochemical and nutritional composition. The addition of 12% orange peel in jam reduced (p < 0.05) the acceptability for all evaluated attributes, as well as overall acceptance and purchase intention. However, OP utilization increased (p < 0.05) the levels of water activity, soluble solids, titratable acidity, and sugars. Soluble solids/titratable acidity ratio, luminosity (L*), and yellow content (b*) decreased in all added OP jams, while red content (a*) increased. No change in the pH and moisture values of the product were observed after OP addition. Ash, protein, lipid, dietary fiber, ascorbic acid, carotenoids, phenolic compounds, and antioxidant capacity values increased after OP addition, while carbohydrate and energy content decreased. A texture test showed that adhesiveness decreased, while gumminess, chewiness, and elasticity increased after OP addition. We concluded that the addition of up to 8% orange peel in jam maintains sensory acceptability similar to that of the standard product. OP addition is a viable alternative to improve some of the product's physicochemical and nutritional characteristics.

Existe diferença entre o estado nutricional de pacientes com doença pulmonar obstrutiva crônica e outras doenças pulmonares? / Is there a difference between the nutritional status of patients with chronic obstructive pulmonary disease and other lung diseases?

Introdução: A doença pulmonar obstrutiva crônica (DPOC) é caracterizada pela lenta e progressiva obstrução crônica do fluxo aéreo, pouco reversível, associada a uma resposta inflamatória anormal dos pulmões e inalação de partículas ou gases tóxicos. Objetivo: Comparar o estado nutricional de pacientes hospitalizados com diagnóstico clínico de DPOC com outras doenças pulmonares. Método: Foram utilizados prontuários com dados referentes às características antropométricas, clínicas e alimentares de pacientes com diagnóstico clínico de DPOC e de outras doenças pulmonares. Para associar os dois grupos de pacientes, foram aplicados os testes T de Student, exato de Fisher e Mann-Whitney conforme a distribuição de normalidade. Resultados: Participaram do estudo 76 pacientes, não havendo diferença estatística entre ambos os grupos quanto à ingestão alimentar (p>0,05). Os pacientes com DPOC apresentaram mais desnutrição, porém sem significância (p>0,05) e a prega cutânea tricipital foi menor entre os pacientes com DPOC (p<0,05). Conclusões: Não há diferença entre o estado nutricional e dietético de pacientes com DPOC e demais doenças pulmonares.(AU)

Introduction: Chronic obstructive pulmonary disease (COPD) are characterized by slow and progressive chronic airflow obstruction, not easy reversible, associated with an abnormal inflammatory response of the lungs and inhalation of toxic particles or gases. Objective: To compare the nutritional status of hospitalized patients with clinical diagnosis of COPD with other pulmonary diseases. Methods: Documents of data regarding the anthropometric, clinical and dietary characteristics of patients with clinical diagnosis of COPD and other pulmonary diseases was used. In order to associate the two groups of patients, T Student, Fisher's exact and Mann-Whitney tests was applied according to the distribution of normality. Results: 76 patients participated, and there was no statistical difference between the two groups regarding food intake (p>0.05), patients with COPD have shown more malnutrition, but without significance (p>0.05) and triceps tick up was lower among the patients with COPD (p<0.05). Conclusions: There is no difference between the nutritional status of patients with COPD and other pulmonary diseases.(AU)
